Abstract
Aims
To compare clinical characteristics and perinatal outcomes between immigrant and Spanish
women with gestational diabetes mellitus (GDM) in a multiethnic population of Barcelona
and to identify factors independently associated with the development of large-for-gestational-age
(LGA) infants.
Methods
Prospective study of women with GDM from five ethnic groups (Caucasian, South-Central
Asian, Latin American, East Asian and Moroccan) at a single institution in Barcelona
between 2004 and 2011. Maternal, gestational and newborn characteristics were recorded.
Results
The cohort included 456 patients. In univariate analyses, Moroccan women had more
frequently a pre-gestational body mass index (BMI) > 25 kg/m2 (76.4%, P = 0.012), while East Asian women had lower BMI (23.41 ± 2.79 kg/m2, P < 0.001), less need for insulin therapy (14.3%, P = 0.013) and the highest rate of spontaneous labor (69.8%, P = 0.014) and eutocic delivery (63.8%, P = 0.032). Also, Latin American women had a higher rate of Cesarean section (52.9%, P < 0.001) and LGA infants (28.6%, P = 0.004), and their newborns had lower umbilical cord pH (7.23 ± 0.06, P = 0.005) and Apgar scores (9 [

], P < 0.01) and a higher incidence of neonatal hypoglycemia (51.4%, P = 0.045). Logistic regression analysis identified pre-gestational BMI (OR: 1.18; 95%
CI: 1.09–1.27), pregnancy weight gain (OR: 1.19; 95% CI: 1.1–1.28) and insulin use
during gestation (OR: 2.29; 95% CI: 1.09–4.82) as predictors of LGA infants.Conclusions
Significant ethnic differences were found in clinical characteristics and perinatal
outcomes of women with GDM. Latin American women had a higher frequency of adverse
perinatal outcomes. Pregestational BMI, pregnancy weight gain and insulin use during
pregnancy were independent predictors of LGA.
